Hi there.
I own a non-steam version of ESO, and my girlfriend is buying the game on Steam to play with me.
Being a South African resident, with more limited internet than other places, I would prefer to copy my files to her than her having to download the entire game.
Is it possible for me to copy my non-steam game files to her, such that her Steam can verify the files as a Steam game?
And how would I go about this process?
